Specification of Letters Patent. I

Application filed November 9, 1912. Serial No. 730,530.-

To all whom it may concern:

Be it known that I, GEoRGEW. BEADLE,

a citizen of the United States, residing at make and use the same.

This invention relates to drying and cooling attachments for paraflining machines for paper cartons or bottles, and has for its ob ject to provide a means by which the bottles will be more eflectually paraflined, as well as more effectually dried and cooled, than tion, and comparatively inexpensive to conhas been heretofore proposed, and one which Wlll be simple in construction, certain in acstruct.

To these ends the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularlypointed out in the claims. v p

Referring to the accompanying drawings forming a part of thisspecification in which like numerals designate like parts in" all the views: Figure 1 is a diagrammatic side elevational view of a machine built in accordance with my invention; Fig. 2 is an end elevational view of the water immersing portion of my" machine; Fig. 3 is a detail sectional view showing the means for rotating the paper cartons n their own axeswhile being conveyed to the machine shown in Fig. 2; Fig 4 is an end elevational view of a portion of the conveyers for the cartons; Fig. 5 is a,sectional plan view of the water immersing machine; ,and

, Figs. 6, 7, 8, 9 and 10 arefragmentary detail views of certain portions of the said water immersing machine. 1

1 indicates any suitable framework in which is mounted aparafiin dipping wheel 2, operating in a paraflin bath 3, all of which is or may be constructed substantially the same as the machine illustrated in my Patent #1,030,636, dated June 25, 1912,

and entitled Machines "for coating cartons. Leading to the paraflining wheel 2, I provide the conveyer 4 passing through the.

inclosed chamber 5, which may be suitably heated as by the gas jets 6 in order to drive out the moisture from the cartons before they reach the wheel 2, and thereby cause said cartons or paper bottles to more readily absorb the parafiin.

6 represents any suitable motor provided with a driving belt 7 for turning the wheel 8 mounted on the shaft 9, provided with the pulley 10, over which passes the driving belt 11. The saidbelt 11 in turn passes over the pulley 12, mounted on the shaft 13 of the paraflin wheel 2, and drives the said paraffin wheel. The cartons when delivered at the point 15 upon the conveyer 4 are carried to the pockets 16 of the said paraflin wheel, are dipped in the paraflin bath 3, and are later delivered to the conveyer belts 17 in any-suitable manner, as for example that disclosed in my patent above. The said conveyer belts 4 and 17 are, or may be, also suitably driven from the motor 6 by the driving belts 18 passing over the pulley 19 pulley 23 mounted on the shaft 24, onwhich Patented Apr. 6, 1915.

is mounted the pulley 25, over which passes the conveyer 4. The said conveyer 17 is driven by means of the pulley 28, mounted on the said shaft 20, all as diagrammatically illustrated in- ,Fig.- 1. The particular driving means of the belts 4 and 17 do not form an important feature of my invention, and

any other. suitable mechanism maybe employed for driving the said conveyer belts,

:as, for example, that employed in my patent above.

As is well known, after the bottles are dipped in parafiin they must be drained of the surplusparaflin in order to save expense.

At the same time the said bottles" must be, evenly coated, or else there will he places not sufficiently covered through which water may penetrate and collapse the paper walls of the bottle. In order that the bottles may be economically drained of their surplus paraffin while passing from the paraffin wheel 2 to the water dipping wheel 30, I in cline the conveyer belt 17, as best shown in Figs. 1 and 4, so that the surplus paraflin will. drain oiit of the mouth of the bottle.

In order to insure the open end of the bot tlebeing located below its closed end, said bottles are placed on the conveyer 4, at the point 15, with theiropen ends all pointing in the proper direction to insure this drain. However, should the bottles rest in one position while thus draining the paraifin and while passing through the drying chamber surfaces of the bottles 32 and thereupon turn the said bottles upon their axes as they travel toward the water wheel 30. It results from this that the bottles are lifted momentarily a slight distance from the conveyer 17, as indicated in dotted lines in Fig. '3, and are slightly turned so that the paraffin settlesequally over all portions of the bottle. I have also discovered that when the paraflined bottles are immersed in a water bath for the purpose of chilling the soft paraffin coating, the water first rushes inside the bottles, and then as the bottles are further immersed it rushes out of the same during the operation of filling and theresuit is the coating is not only roughened and rendered unsightly, but since the said coating is quite thin it is liable to be raised into pin holes, or weakened patches, which are liable later to break through and permit the contained liquid to penetrate the walls of the bottles and collapse the same. To avoid this most serious objection, and at the same time to impart .a much higher and more sightly polish to the said coating, 1 have discovered that it is only necessary to partly immerse the said bottles while rotating the same upon their axes. That is to say, if

the water is allowed to only partially fill the 1 bottles when the latter are lying in a horizontal direction,'and if the bottles are at the same time rotated upon their aXes, the paraffin coating is constantly chilled and an exceedingly high polish is imparted thereto, while the above roughnesses are entirely avoided. In order to automatically and expeditiously accomplish this more desirable result, I have provided the water dipping wheel now to be described. The said wheel is mounted upon the shaft 9 and rotated by shown in Fig. 2. The said cam guide-way holds the stud shafts 35 retracted against the tension of their springs 40, and thereby holds the'bottle holding heads 41 likewise retracted until the heads 38 leave the guideway 39, which is at a point immediately under the delivery end of the conveyor 17, as will be more fully stated below. The said water wheel 30 is also provided'with a ring 42 forming bearings for the stud shafts '35, and with a similar ring 43 supplying bearings for readily rotatable heads 44 similar to the heads 41. The said heads 41, however, are preferably provided with roughened or rubber-like surfaces 45 (see Fig. 5) for more firmly gripping the'bottles without injuring the same. it

Passing from side to side of the casing 46,

in which the wheel 30 is mounted, are the rods 47 and 48 on which are mounted the delivered onto said fingers, as illustrated in Fig. 2, whereupon the retracted head 41 is brought by the rotating Wheel opposite the end of the delivered bottle, and as it is released from the grip of the cam-way 39 at this moment, it seizes said bottle between itself and its companion head 44 and carries the said bottle around with the wheel. The fingers yield against the tension of their springs 53 to permit this action, and the fingers 56 likewise yield against the tension of their springs 58, all as will be clear from Figs. 6 and 7. The parts are so timed that as one bottle is thus caught between one pair of heads 41 and 44 and the said bottlemoved out of the water, another bottle is likewise delivered onto the fingers 52 and 56, and is in turn caught between a like pair of heads and likewise moved out of the Way. The process continues until the bottles finally reach the position best illustrated in Fig. 8, in which position the revolving and rising bottles first strike the fingers 60 mounted upon the shaft 61 and turn the same against the tension of theirsprings 62. At about the same time, the same bottle strikes the inwardly curved end of the fingers 63 mount ed upon the rod 48 and moves the same against the tension of their springs 65. The bottles next pass to the position illustrated in Fig. 9, whereupon the fingers 60 have been disengaged from the bottles-and occupy a position underneath the same, and whereupon the tension of the spring 65 causes the fingers 63 to eject the bottles along the fingers 60, as illustrated in Fig. 10, as well as to deliver the same on the conveyer 70, as best illustrated in Fig. 5.

During the movement of the bottles from the first position, when they are caught by the heads 41 and 4:4, to their last position, when they are delivered upon the conveyer 70, they are only partially immersed in the water bath 73 which is so regulated that it I only about half fills the lowermost bottle.

And also during thissaid movement, the pinions 36 are in constant engagement with the circular rack 37 and are rapidly rotating the said bottles upon their axes. It results from this that all splashing of the water inside the bottle,'and the consequent raising of only gets rid of the moisture, but it shrinks the package and therefore makes the joints tighter before they receive paraflin. It

i will further be clear that the chilling efi'ect of the water prevents the parafiin from soaking too far into the paper walls of the bottle, and therefore less parafiin may be used to render the bottle water tight. In addition to this, the water cooled coating of paraflin is found to be less porous than an air cooled coating, and it is therefore better able to hold the contained liquids. Further, the roughened or rubber-like disks with which the heads 41 are provided not only afford the necessary friction to turn the bottles on their axes, but they prevent water from getting into the crimped bottom walls with which these bottles are provided, and thereby prevent the water from softening the paper walls of the bottle.

It is obvious that those skilled in the art may vary the details of construction, as well as the arrangement of parts, Without departing from the spirit of my invention, and therefore I do not wish to be limited to the above disclosure, except as may be required by the claims.

What I claim is 1. In a cooling meansfor coated cartons, the combination of a wheel provided with seizing means for the cartons; a water bath into which said means is adapted to dip said cartons; means associated with said seizing means adapted to retract the latter after the dipping operation; and means to rotate said cartons on their axes during the said dipping operation, substantially as described.

2. In a cooling means for coated cartons,

the combination of a wheel provided with.

seizing means for the cartons; a water bath into which said means is adapted to dip said cartons; means associated with said seizing means adapted to retract the latter after the dipping operation; means tocause said cartons to leave the wheel after said seizing means is retracted; and means to rotate said cartons on their axes during the said dipping operation, substantially as described.

In testimony whereof, I affix my signature, in presence of two Witnesses.
